or diminished in sizef-by increasing or d iminishin'g the number ofsections and in which the smoke -consumingportion-of the heater orboiler is. cast integrally therewlth,

said smoke consuming portion being likewise constructed in sections andadapted to have the sections connected in like manner to the heater orboiler sections.

Another object of my invention is the provision of means for drawinghotair into vthe passage receiving the outer air,l which -hot airthoroughly mixes w1th the outer air and thus insures a quick heating ofsaid outer air in its course of travel to the fireplace.

Other objects are to provide a smoke consuming heater or boiler of thesectional in which the smoke 'consuming ortion thereof is cast insections integral wlth the heater or boiler sections, and to otherwiseim rove on smoke consuming heaters and bo ers now in use.

To these ends the invention consists in equipping a sectional heater orboiler w1th an air passage or passages, said air passage or passagesbeing formed in sections correspending to the boiler sections andintegral therewith.

lt further consists in the provision of means for introducing hot airinto a passage or passages fromthe fireplace so as to commingle with theexterior air drawn into said passage or passaoes, for the purpose ofmore 'readily heating the exterior air in its course of travel into thefireplace. V i i It further consists in the novel features ofconstruction, and in the arrangement and (ombination of parts to`behereinafter decribed and more particularly pointed out in the subjoinedclaims.

ile` the above described ligures illustrate the nature of `my inventionand the manner of applyin the-same to asectional water heater 'or boierof a particular type, it is fullywithin the province of my inventionto apply the same to any other form of sectional heater, boiler orfurnace in which the consumption yof smoke and unconsumed gases isdesirable, and itis to be 4un-A derstood thatthe constructionillustrated is merely the preferred embodiment of my invention'for theparticular type of boiler or heater shown.

'Referring now to the drawings in detail, like numerals of referencerefer to -like parts in the several figures.

The reference numeral 12 designates the ront section, 13 the rearsection, and -14 the intermediate sections of the heater or boiler, saidheater or boiler being of the sectional type of which there are many nowin use,

the particular constructiony of the several4 sections being immaterialto the application of my inventionv thereto. The sections of heaters orboilers of this type are usually connected by means of nipples, and profvision is made for the assage of the heat through the assembled oilersections so as to heat or boil the water therein, all of which isunimportant to .my present invention.

When the sections of the heater or boiler are assembled, a fireplace 15is provided beneath which is the usual ash pit 16 separated from thefireplace by the fuel grate 17. The

rear section 13 of the heater or boiler has cast integrally therewithand on the inner face thereof a conduit 18 which extends from onevert-ical edge of the said section to 'the other, and spaced from saidconduit 18 is a second conduit 19 formed in'two spaced sections 20. 21.the space separating said sections being at ,the center of the rearboilersection. From this space the two sectionsextend Yino positedirections coextensive with the co uit 1 8- to the opposite ver-L091/,rie

tical edges ci he rear boiler section. Passng heated by the impingingv{"iinnes of the ing through he rear section ccnraly of said space is anopening and cstending through said opening from the inside of the boilersection is one arin ci: a T-shaped fitting Q3, the other portion or headoft' said fitting occupying the space between the tivo spaced sectionsof the conduit lQ. iitiing made hollenand serves to inreduce air intothe two spaced sections ofi J conduit 1 9 and in order to cause the heig'ed 'from the fireplace to be drawn into said conduit the T-shapedfitting has openings 24 facing dow'nw ardly and. also nozzles 25threaded or otherwise secured thereinto which are ar ranged in onf,Yaire relaion to said openings 2li, The a 4 through said 'shapcdfitting' passes through the nozzles and has a. tendencv to draw the hotfrom the fireplace into the conduit i9 through the openings Qa at thebottom of said 'shaped fitting.

The front section of the heater or boiler (s provided with the usualopenings for introducing fuel into the replace, for prou viding accessto the ash pit, and for cleaning or otherwise attending to otherportionsv of the heater or boiler. The intermediate sections of theVheater or boiler have side legs 2G at opposite sides of the fireplaceand on the inner face of each leg is cast a conduit 27 which is arrangedin line with the conduit 1 8 on the inner Wali of the rear section andspaced from each of said conf duits on the legs of the said sectionsiscast another conduit 28 in line with the conduit 19 on the inner faceof said rear section. The conduits of adjoining sections ave connectedtogether by push nipples 29, said nipples being similar to those usuallyemployed in connecting the sections of the heater or boiler together.The foremost section having the conduits thereon are provided at eachside of the replace with a U- shaped connector 30; said connectorshaving reduced ends 8i which enter the conduits and being held in placeby set screws 32, or otherwise.. These Usl-raped connectors conneet the.upper and lower conduits tegel-hen By thus constructing the conduits andcon-- neciing the saine, two passages provided which enend from pointnear the front of one side Wall rearwardly and around the rear Wah io a.similar point of the other side wail. The conduits forming one of thepassages haring air escape apertures 33. y

in the construction described., the exterior air is drawn into thepassages through the T-itting 23 and in passing-through the nozales insaid iittings, creates suction te draw into said passage the hot airfrom the fire-y place. The hot air and exterior air there .forecommingle in their course through-the imperforate passage and passforwardly along both sides of the heater or boiler, bs-

entering from the exterior in the fireplace. The air thais thorly heatedthen passes through the U- pcd connectors and enters the perforatedsage, from which it escapes through the l rorations thereof and inpassing out into she fireplace causes the unconsumed products ofcombustion to be ignited. This greatly increases the heating capacity ofthe boiler and tends to save. considerable uel.

In the preferred embodiment of my invention described, the air passagesare arranged so that an inperforate portion and a perforated portion areprovided, the imperforate portion being adapted to be subjected to theheat of the fireplace so as to thoroughly heat the air passingtherethrough preparatory to passing into the perforated portion andescaping therefrom. adconiplished by extending the passages in spacedrelation and connecting them at'two points so as to make themsubstantially endless, introducing air at one point and alloiving it toescape through a plurality of p'erforations, for the purpose described.

F or the purpose of referring to the air passages disclosed in myinvention by a generic term, I will refer to them as tubes" inv theclaims, by which term I intend to include all constructions, in whichair passages are formed.

Having thus described my invention, what I claim is,-
